It is ap- plicable to wool. An alternative method is specified in 6.3 to provide a milder test suitable for assessing the effect
22、of chromium salts in such concentrations as might be found when shading. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 105.
